Here’s a fun new discipline that will grow in years ahead — Smallbore F-Class with .22 LR rimfire rifles. Rest-supported prone rimfire matches have been held around the world for quite some time, but only a few years ago was the discipline officially codified in the NRA Smallbore Rulebook. And the first-ever Smallbore F-Class National Championship was held in July 2018 in conjunction with the Smallbore Nationals at Camp Wa-Ke’-De in Bristol, Indiana. The Nationals involved multiple days of prone shooting at 50 meters and 100 yards. For more information read Hap Rocketto’s Shooting Sports USA Smallbore F-Class Report.

Smallbore F-Class competitors may shoot F-TR style with a bipod, or use a front rest. In the above photo from the inaugural NRA National Championship you can see a shooter with SEB Coaxial Rest at top, with a competitor using a low-profile bipod at bottom. Note the extended handle used to adjust bipod elevation. This is not a coaxial joystick, but rather a long handle attached to the mariner wheel.

Smallbore F-Class — The Future Looks Bright
With the high cost of centerfire ammunition, and the limited number of 1000-yard (or even 600-yard) ranges, we can envision that Rimfire F-Class will become a popular event at ranges across the country. Clubs don’t even need benches — just a 100-yard target bay and flat ground for the shooters. You can start with an inexpensive rimfire rig and Harris bipod. Then work up from there. Here is a custom rimfire F-TR style rig that belongs to F-Class ace and past centerfire F-TR National Champion James Crofts.

Rimfire F-Class and Fun Prone Matches with Front Rest or Bipods

Rimfire F-Class offers the fun of centerfire shooting at a much lower cost. Shooting is done prone with either a front rest or a bipod. You can shoot a relatively inexpensive rifle such as a CZ 457 MTR, or a custom build that has the same design features, weight, and ergonomics as a full-size F-TR or F-Open rifle. The choice is yours. We like shooting smallbore F-Class, because you can find decent .22 LR ammo for just $0.20 per round. By contrast, you’ll probably spend at least $1.20 per round for F-Class centerfire ammo (counting bullet, powder, primer, and part of the brass cost).

Top-Tier Vudoo V22-S Target Rifle for Rimfire F-Class

Vudoo Gun Works now offers an impressive .22 LR Single Shot Target Rifle that should prove ideal for rimfire F-Class (Open division). It features the new V22-S single-shot action, McMillan stock, and Flavio Fare BR-VS trigger.

Rimfire F-Class in the Canary Islands

This video comes from the Canary Islands, part of Spain. The voice-over is in Spanish but there are English sub-titles. The host explains: “In this video we summarize the main characteristics of this [shooting sport] that is practiced at 50 meters, 100 meters, and 200 meters with your .22 LR. Learn how to prepare your rimfire carbine and learn how to score your own targets by following our simple explanations. In another video we will delve into shooting techniques, shooting accessories and field accessories.”

Here is another rimfire F-Class video from the Canary Islands. This shows how the sport can be done with a variety of rimfire rifle types, even including a .22 LR AR clone. Some shooters are using a wide-base bipod, others are using normal Harris-type bipods, while others are using a large, benchrest-style front rest.

Rimfire F-Class-Style Local Fun Match in Oregon

In this video, F-Class John shoots an F-Class-style local fun match in Oregon. He is using a .22 LR rimfire rifle that has a full-size stock very similar to his custom F-Open centerfire rifles. This allows him to easily switch from centerfire F-Class to rimfire prone shooting with front rest and rear bag. The local fun match rules are a little different than an official F-Class match, but the shooting skills required are the same. Shooting this kind of local rimfire match allows John to keep his F-Class skills at a high level at a fraction of the cost of shooting centerfire F-Open.

Rimfire F-Class in Russia

NOTE: This video was filmed in Russia. The dialog is in Russian (without English subtitles), but it is still interesting to watch. Shooting F-Class with .22 LR ammo has become popular in Russia and other parts of Europe. You can have fun on a relatively short (200m) range with low-cost ammo.

Smallbore F-Class Course of Fire
The Smallbore F-Class Nationals was completed on paper targets at 50 yards and 100 yards. According to Shooting Sports USA: “The tournament ran during the any sight and metric phases of the 2018 NRA National Smallbore Rifle Championships, featuring a daily course of fire which mirrored the sling shooters, 40 shots at 50 meters on the A-50 target, a Metric Dewar, followed by 40 shots at 100 yards on the A-33 target. Although the international targets were shot throughout, the first two days were titled ‘conventional’ and the last two ‘metric’.”

The specifics of the match such as rifle requirements, rests, and sights may be found in the Provisional Smallbore Rifle F-Class Rules (Section 23), found on page 65 of the current NRA Smallbore Rifle rulebook. Any rules not covered in Section 23 will [reference] the normal rules of Sections 1 through 22.

Long-Term Powder Storage — Important Guidelines to Follow

Western Powders Blog SAAMI Storage

SUMMARY: Powder can have a very long shelf life. You need to watch for changes in smell and color. A reddish tinge, almost like rust on the powder, is a bad sign, as is a foul odor, not to be confused with a normal chemical smell. Either of these signs indicate it is time to dispose of your powder by means other than shooting.

Ever wondered about the stability of the propellants in your reloading room? There are some important things you should know about powder storage, to ensure consistent powder performance and safety. Western Powders (which has been acquired by Hodgdon) published an informative Q & A series entitled Dear Labby: Questions for our Ballistics Lab . Here are some excerpts that pertain to powder storage and shelf life. Worried that your powder may be too old? Western’s experts explain how to check your propellants for warning signs.

Proper Powder Storage

Q: I live in southern Arizona where it is very hot. I am told powders will become unstable if stored in an area not air-conditioned. My wife says no powder or primers in the house. Can powder be stored in a refrigerator? What about using a fireproof safe? I would appreciate your ideas. — M.C.

Lab Answer: SAAMI guidelines are pretty clear on issues of storage. They recommend storing smokeless powder in containers that will not allow pressure to build if the powder is ignited — ruling out gun safes and refrigerators.

In their original containers, the lifespan of smokeless powders is quite long, even in hot, arid climates. In fact the lifespan is typically longer than the average handloader would need to store them. Stored safely in a garage or outbuilding, your powder should last years. If you see the powder developing a reddish tint, or giving off a foul odor, it is time to discard it.

Clumps in Powder Container

Q: I ordered some of your Accurate 1680 powder back about in December. I just now opened it … and it is full of clumps. My knowledge tells me that means moisture. Am I wrong? I just now broke the seal and it has been stored in a ammo can with desiccant packs around it and a dehumidifier running 14-16 hours a day. I can’t imagine this being my fault, if this does indicate moisture. I don’t know if the pink part on the label is suppose to be red or not, but it is definitely pink, so if it was red I am wondering if I was shipped an old container? I hope that this isn’t bad and I am stuck with it…

Lab Answer: All powder contains a certain amount of moisture. When the powder is stored or during shipping, it can go through temperature cycles. During the cycling, the moisture can be pulled to the surface and cause clumping. Clumping can also be caused by static electricity if too dry or the powder has limited graphite content. You can break up the clumps before metering and they shouldn’t be a problem. This will not affect the powder performance, so your product is fine. Accurate 1680 labels are designed in Pink. As a side note, specification for testing powder is at 70° F and 60% humidity.

Shelf Life and Packaging Dates

Q: Does powder ever get to old to use and what identifying marks does your company put on the canister for when it is made, You have helped me out a while ago when I asked about keeping my cowboy shooting under 950 fps and it works great less stress on the hand and the recoil is very minimum. — R.B.

Lab Answer: On one pound bottles, the number is on the corner in a silver box. If the powder was poured today, it would read 012815 followed by a lot number. The whole number would look something like 012815749. Eight pound bottles have a sticker on the bottom with an obvious date code. The lot number appears above the date.

Flash-Hole Fix — Remove Case Flash-Hole Obstructions

Flash-hole reamer

Even with high-quality brass from Lapua, Peterson, Norma, Alpha and RWS, occasionally you may find one or two cases per box which have a small flake or obstruction in the flash-hole. This will appear like a thin crescent on one side of the flash hole (see photo). You should inspect ALL new brass before loading to identify any pieces with a partially-obstructed flash hole. It’s a good idea to remove any flake or thin crescent left as an artifact of the flash-hole forming process. Because the flash-hole itself is normally centered and of the correct diameter, it is not necessary to ream the flash-hole to a larger diameter. All you really need to do is remove the small obstruction(s). This can be done quickly with inexpensive tools.

Use a Small Pin Vise to Remove Flash-Hole Obstructions
Folks have asked if there is a tool that can remove obstructions from a Lapua small, BR-sized flash hole without opening the hole size. The Lapua PPC/BR flash hole is spec’d at 1.5mm, which works out to 0.059055″. Most of the PPC/BR flash-hole uniforming tools on the market use a 1/16″ bit which is nominally 0.0625″, but these often run oversize — up to 0.066″.

If you want to just clear out any obstructions in the flash hole, without increasing the flash hole diameter, you can use an inexpensive “pin vise” with an appropriate drill bit. For $0.99 ($0.50 on sale), eHobbyTools.com sells a 1.5mm drill bit, item 79186, that matches the Lapua flash hole exactly. Other vendors offer a #53 pin vise drill bit that measures .0595″ or .060″ (depending or source). An 0.0595″ bit is close enough. You can find pin vises and these small-diameter drill bits at hobby stores.

Pin vises Lapua Flash hole

For quite some time, Sinclair Int’l has sold a similar device for small (PPC and BR-size) flash holes. Like the 07-3081 unit for large flash holes, the 073000 Reamer for small flash holes works from the outside, so it can index off the primer pocket. It reams to .0625″, and also costs $29.99. The standard dimension for Lapua 220 Russian and 6mmBR flash holes is 1.5mm or .0590″. This tool will permit standard-size decapping rods with .0625″ tips to work without binding. However, note that both Forster and Redding normally supply .057″ decapping pins with their PPC and BR dies. So, it is NOT necessary to ream your Lapua BR/PPC flashholes, unless you prefer to do so for uniformity. It IS, however, a good idea to check BR/PPC flash holes for burrs before loading the first time.

AccurateShooter Sinclair Flash Hole Reamer

NOTE: If you purchase either the 073081 or 073000 Sinclair Flash Hole Reamer tools, we recommend you mic the cutter tip before you process a bunch of cases. Sometimes a tip comes through that is oversize. This will ream the flash holes larger than you may intend.
